Half marathon

Hello everybody!I am looking for an answer with this doubt..Its a good time to do the half marathon in 1 hour and 50 minutes training at least three monthsRunning three days a week?I have being running the last half year not regulary Thanks

Yes 1 hr 50 is a reasonable time. With only 3 running sessions per week you'll have to be careful to balance speed and distance with recovery. I'm also training for a half, currently doing 3x runs per week, but start increase mileage, days to four and speed training next week. Good luck.
